RIVET-SETTING MACHlNE.

SPECIFICATION forming part of Letters Patent No. 394,743, dated December 18, 1888.

Application filed May 24, 1888. Serial No. 274,996. (No model.)

To all whom it may concern:

Be it known that I, ALBERT M. IVHITE, of \Vaterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improved Rivet-Setting Machine, of which I declare the following to be a a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvements in rivet-setting machines in which the rivets are conveyed by a chute to a receiver, where they are held in position to be driven by the plunger; and the invention consists of a rivet-setting machine having its receiver constructed substantially as described and claimed.

In the accompanying sheet of drawings, Figure 1 is a side elevation of a portion of the machine, showing the receiver in section; Fig. 2, a plan view of the receiver; Fig. 3, a front view of the receiver, partly in section in the plane 00.1, Fig. 2; Fig. 11:, a plan view of the separator and a portion of the chute; Fig. 5, a cross-section in the plane mm, Fig. 4; Fig. 6, an edge view of the chute and separator.

Similar letters of reference indicate like parts in the several figures.

It is essential in the rivet-setting machines to which this improvement is adapted that the rivets should pass one by one and at regular intervals from the chute into the receiver, so that each time the plunger rises afterhaving driven a rivet another rivet will be deposited in the receiver ready to be driven by the plunger when it again descends. Each rivet drops into the receiver with its piercing end downward, and is so held by thereceiver to await the action of theplungcr. The receiver is constructed at the outer end of an arm, A, bolted to the frame 13 of the machine. This arm terminates in a block of suitable thickness, in which is formed a cylindrical perforation, a, with a channel, 1), opening into it from the rear. In the edges of the block on each side, and in range with the perforation a, are cut recesses, in which are pivoted guides 0.

-These guides extend under the arm A and form a conicalshaped bottom, closing or nearly closing the perforation a, and they are provided with wings 0 arms (2 and connected near their lower extremities by a spring, 6.

Through slots f in the walls of the perforation or chamber a project narrow springplates h into the chamber, the outer ends of these plates being riveted to the wings d of the guides c. The receiver is located between the plunger C and anvil I) of the machine.

A separator is attached to the chute some distance above the receiver. The rivets pass from a reservoir, where they are contained inv bulk, into the chute with their piercing ends upward, and before they reach the receiver are inverted by means of suitable mechanism, which it is not necessary to describe, since such mechanism forms no part of this invention. The separator is designed to arrest the progress of the rivets as they slide down the chute in a row and allow but a single rivet to pass on and enter the receiver for each operation of the plunger.

No particular form of separator need be employed; but the one shown in the drawings, and designated by E, is simple and effectual.

\Vhen the machine is in use, the rivets collect in the chute above the separator, as shown in Fig. 4, and as the plunger rises the plate at turns on its axis and draws upward the rod 112, whereby the separator is caused to rotate slightly and the particular finger of the separator which obstructs the passage of the rivets moves out of the way and the lowest rivet of the series passes down the chute; but only this single rivet is released at this time, because the next finger of the separator is interposed across the passage below the succeedin g rivet, and it and the other rivets above are thus held back till the plunger again rises and the separator is caused to rotate further, when the operation just described is repeated. As the rivet enters the receiver, having been reversed, as before mentioned, its stem passes through the channel I) and its head is supported in a horizontal position by the inner ends of the spring-plates 71, where it remains ready to be driven by the plunger. The plunger, descending, meets the head of the rivet and forces the rivet through. the receiver, the plates h and guides c yielding gradually to the pressure of the plunger and keeping the rivet in a vertical position till, finally, the rivet is driven through the garment or material beneath the receiver and upset either directly against the anvil or within the shell of a button restin upon the anvil. The plunger then rises and the operation continues as described.

Having" now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In the receiver of a rivet-setting machine, the combination of a chamber, o with slots f in the walls thereof, and yielding plates 7:,attached at their outer ends to suitable supp0rts,their inner ends projecting thronghthe slots f and being adapted to support a rivet, sul istantiall v as and for the purpose d eseri bed.

In the receive r of a ri vet-settin mach ine, the combination of a chamber, (1, with slots f in the walls thereof, yielding plates 71, projecting' through said slots and adaptcalto support a rivet, and pivoted arms (I, to which said plates are attached, substantially as and for the purpose described.

3. In the receiver of a rivet-setting lllfiCilillQ,

the combination of the chamber a with slots in the walls tl'iereo'l, yieldinplates 71,1)1'0j6Cl'r ing through said slots and adapted to support a rivet, and springaregulated guides e,having' wings (I, to which said plates h are attached, substantially as and for the purpose described. 4. In the receiver of a ri\ ;it-settingmachine, the mimbii'iation ot the arm A, provided with the chamber (1 having slot-s f :in the walls thereof, and the channel. b, the yielding plates 71, the pivoted guides and the spring e, substantially as and for the purpose described.
